Hello Pablo; Is the Wago coupler a 750-375 Profinet module? The coupler's manual states that they support redundancy (over Profinet) when the master has a MRP ring set up; Here is a link to the 750-375 manual: https://docs.rs-online.com/4464/0900766b813d2a3d.pdf And here is a Siemens manual on Profinet configurations for the S7-400H systems. https://support.industry.siemens.com/cs/ww/en/view/90885106 The screenshot below shows the minimum setup for a MRP ring with a S7-400H. There are more complex arrangements you can study in the manual. And the following document should guide you in creating a MRP ring in your S7-400H system: https://support.industry.siemens.com/cs/ww/en/view/19292127/35377011083 Hope this helps, |

Hi pablochavez I highly doubt that your WAGO 750-377 supports so called S2 redundancy which is what you need to have both H-CPU's being able to establish an Application relationship with the I/O device (MRP is handled on the physical ring layer and is a totally separate thing to S2 redundancy). Suggest you check with WAGO if S2 redundancy is available or will be released soon (perhaps as a firmware upgrade). If not though, you are out of luck and will have to use for example an ET200SP instead. See also THIS FAQ for more and to be fair to WAGO, even Siemens has been dreadfully slow in releasing I/O devices that support S2. |
